ABRASION" UNIT FOR'RAIL JOINTS.

Application filedNovember 17, 1 22- Serial No. 601,600.

To all whom it may concern.

Be it known that I, BENJAMIN WOL- HAUPTER, a citizen of the United States, re-

siding at New Rochelle, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Abrasion Units for Rail Joints, of which the following is a specification.

This invention relates to rail joints, and more particularly to an improved abrasion unit or wear filler having novel features of construction and design that render it of special utility in connection with standard types of joint "bars having a wedge fit in the fishing spaces of the rails, thereby to compensate for the wear which is usually focused on the'bearing faces of the bars at or near the rail ends.

A primary object of the invention is to rovide a simple, practical and reliable unit unctioning as a chafing guard or wear filler adapted to compensate for the wear usually imposed on the joint bars, thereby materially increasing the life of the joint. To that end the invention contemplates a novel sectional construction engaging the underside of the rail head and the upper side of the base flange of the rail, and vertically yieldable or adjustable to permit of "the ac splice bar properly drawing into the fishing space of the rail as wear occurs.

Inthe above connection the invention contemplates a special formation of the verticalweb portion of the unit which adequately provides for the horizontal shifting or adjustment of the unit as a whole or the divided sections thereof individually, as well as providingfor the diminution or contraction of the vertical height of the unit as the latter is moved into engagement with the converging faces of the rails defining the fishing spaces thereof.

A further object of the invention is to provide an abrasion unit designed and formed to permit of the ready replacement of any of the sections of the unit, or as previously indicated, the shifting of, one of the parts thereof longitudinally in either direction independently of the other between the rail and the bar, thereby giving a wide range of vmanipulation for repair and adjustment. With the above which, will more readily appear as the nature of the invention is better understood,

and other objects in view I the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed. 7

A preferred and practical embodiment of the drawings is shown in the accompanying drawings, in which Figure 1 is a perspective view illustrating one form of the invention.

Figure 2 is a bisected vertical sectional view of the construction shown in Figure 1.

Figure 3 is a perspective view illustrating a modification of the invention.

Figure 4 is a bisected vertical sectional view ofthe construction shown in Figure 3. Figure 5 is a side elevation with the joint bar removed illustrating a still further modification of the invention, the dotted line in this figure indicating the ends of the joint bar to illustrate greater length of the abrasion unit which'is a feature applying to all forms of the invention.

A distinctive feature of the invention is to provide a divided abrasion unit comprising relatively thin hard metal sections adapted to be positioned between the splice bar and the rails for receiving the wear usually imposed upon the head and foot portions of the bar by the chafing action imposed thereon by the movement of the rail under. passing wheel loads. In that connection the invention contemplates the use of sections of minimum uniform thickness throughout, thereby providing a construction that may be easily rolled and at the same time utilizing a minimum amount of metal. Obviously, these general features may be embodied in various structural forms and therefore the drawings are only illustrative of certain practical structures available for use with'standard joint bars.

lherefore, by reference to the'accompanying drawings, itwill be seen that it isproposed to provide a wear unit designated generally as A and consisting of the upper and lower sections B and C, the'same being made of relatively thin. hard metal. and adapted to be used atthe head andfootfof the joint bar respectively to protect the"lat-- ter fro1n-,direct engagement .withthe rail.

As shown in Figuresll and 2. theintermediateor web portion of the upper andlower sections Band 0 maybe of. special formation to provide an interlocking engagement-with 45 and foot of the joint bar from contact with the rails in all adjusted positions of the "tongues .D adapted to 'fit into suitable recesses or notches D in the web or skirt portion W of the upper section B, sufiicient clearance being left at the ends of the tongues D, as shown, to admit of adjustment. Thus, the upper and lower sections Band C are detachably interlocked so that one section may be removed or replaced independently ofthe other, andv yet when the units are assembled in the joint..they are effectively held against unauthorized creep- 'tionsB and C into use.

installed the bolts E and IE will be posi-v ing or shifting, but, of course, the whole unit 'is capable "of being shifted longitudinally. V

The tongue portions D of the lower section- C are shown provided with suitable openings 1, 2, 3 and i for receiving the joint bolts. The openings 1 and 3 are adapted to receive the bolts E and E in the normal installation of the unit, while the bolt holes 2 aud t are provided for the purpose of permitting the longitudinal shifting of the unit to bring fresh unworn portions of the sec- VVhen the unit is tioned in the open spaces or clearances pro- .vided by the formation of the tongues D in the web of the section, and when the interlocked sections B and C are to be shifted longitudinally the bolts E and E are withdrawn from theopenings 1 and 3 thereby to permit the holes 2 and d to register with the bolts E and E whereupon the bolts are replaced. 1 V

In order to adequately protect the head unit, it will of coursebe understood that the members 13 and C constituting the unit are of greater length than the normal lengthof the joint bar.

A further embodiment of the invention is illustrated in Figures?) and 4 of the drawings from which it will be observed that the unit A consists of the upper and lower sections B and C, the web or skirt portions D and D of which-are provided with the notches F for receiving the lockingplates Y matching locking plates G may be square,

G, preferably carried by the joint bolts E E E and E". The said notches F and as shown in the drawing, or they may be obviously made hexagonal, round or any other suitable shape, and may be applied to one or more, or allot thebelts as desired, the fundamental purpose being to provide an intermediate key for establishing an'interlocking engagement between the upper and lower sections B and C. 7

One of the distinctive features of the type of lock for the upper and lower sections B and C shown in Figures 8 and 4c, is that it provides for readily shifting either the upper or lower section independently of the other. thereby making a construction wherein the upper and lower sections of the unit may be adjusted longitudinally from time to time, as wear occurs, without the necessity of shifting the entire unit.

A further form of the inventiong'which provides for a more minute longitudinal adjustment'of the sections B: and C',either as a unit or independently of each other, is shown in Figure 5 of the drawings. In this embodiment the upper and-lowersections l3 and C have the web portions. D formed with serrations. or teeth ll for engaging with similar serrations or teeth on the locking members G carried by the bolts E E etc. Obviously, this type of "construction provides a wide range of longitudinal adjustment for e ther the upper or lower section of the unit. and atthe same time'the adjustment maybe effected toa minute degree, thereby making itpossible to more fully utilize all of the available unworn port-ions of-the'sections. V V 7 Thus, it will'be seenthat in all forms herein described the webof the unit which permits the vertical yielding thereof is uti lized as the locking connection between the upper and lower metal sections.

7 From the foregoing-it will beapparent that the novel and distinctive feature of the present invention is to provide an abrasion unit or wear filler consisting of'sep'arable sections'which may be adjusted simultaneously or independently to bring fresh uni worn portions thereof intense;- and may also be replaced independently to save the least worn section for further Without further description it is thought that the features and advantages ofthe invention will be readily apparentto those skilled in the artand-it will of course be un derstood that'changes in the form,- proportion and minor details of construction may be resorted to withoutdeparting-from the spirit of the invention or scope of'theappended claims.

I claim: 1. ln arail joint, the jointbar'and the rail ends, of anladjustable divided'metal abrasion" unit bridging the joint between the rail ends and comprising separate independently removable and replaceable wear sections. 4 2. In a rail joint,-'the combination'with the joint bar andthe rail ends, of'a' divided metal abrasion unit consisting of separatethe combination with i upper and lower wear sections bridging the joint between the rail ends and having a relative longitudinal adjustment, and means between the two wear sections for effecting an interlock therebetween.

3. In a rail joint, the combination with a joint bar and the rail ends, of a divided longitudinally adjustable metal abrasion unit of greater length than the joint bar.
